KLEAN JOINT & MUSCLE
- Klean Athlete Klean Joint & Muscle combines 480 mg of VitaCherry®, 400 mg of TamaFlex®, and 4 mg of AstaReal® astaxanthin to support joint comfort and exercise recovery. TamaFlex® is particularly interesting because clinical research suggests potential improvements in joint discomfort and mobility, while tart cherry compounds may help reduce exercise-induced muscle soreness.
Its NSF Certified for Sport designation is an advantage for competitive athletes. However, the evidence supporting this exact combination is limited, and results from individual ingredient studies may not translate directly to the finished product. Overall, it's a reasonable option for active individuals seeking joint and recovery support.
KLEAN COLLAGEN+C
- Klean Athlete Klean Collagen+C provides 15 g of hydrolyzed bovine collagen and 50 mg of vitamin C per serving. This combination supplies collagen-specific amino acids alongside a nutrient required for normal collagen synthesis. The 15 g dose falls within ranges studied for joint and connective tissue benefits, while NSF Certified for Sport offers additional quality assurance.
However, collagen is an incomplete protein and should not replace whey or other complete proteins for muscle growth and recovery. Evidence for joint benefits is promising but inconsistent, particularly in healthy athletes. Overall, it's a reasonable option for individuals prioritizing connective tissue support rather than muscle protein synthesis.
